The vulnerability, under active attack, enables bad actors to take full control of systems running the vulnerable Firefox versions. The critical flaw patched earlier this week ( CVE-2019-11707) is a type confusion vulnerability in the Array.pop, which is an array method that is used in JavaScript objects in Firefox. Martin said that a more detailed analysis will be released next week. “We walked back the entire attack, recovered and reported the 0-day to firefox, pulled apart the malware and infra used in the attack and are working with various orgs to continue burning down attacker infrastructure and digging into the attacker involved,” he said on Twitter. We’re also releasing a set of IOCs that orgs can use to evaluate their potential exposure. We are working to notify other orgs we believe were also targeted.

“When combined with additional vulnerabilities this could result in executing arbitrary code on the user’s computer,” according to Mozilla. The flaw “can result in the non-sandboxed parent process opening web content chosen by a compromised child process,” according to Mozilla’s advisory. The high-severity sandbox-escape flaw stems from insufficient vetting of “Prompt:Open” inter process communication (IPC) messages, which are passed between different processes on the browser. However, both vulnerabilities were discovered by Coinbase Security, who said that the flaws were being used in active spear phishing attacks targeting Coinbase employees. The vulnerability (CVE-2019-11708) is separate from a critical flaw under active attack that was patched earlier this week ( CVE-2019-11707). Mozilla has fixed a high-severity vulnerability in its Firefox browser being actively exploited in the wild.
